Microstructure and component analyses of the PEEK-Ag+. The surface of the PEEK-Ag+ was qualitatively assessed using energy dispersive X-ray analysis (EDX) (A). The film consisted of Ca, P, O, C, and Ag. Inductively coupled plasma atomic emission spectrometry (ICP-AES) indicated that the Ag+ ion content in the HAp film was dependent on the AgNO3 concentration used (B). A peeling test showed that the HAp adhered poorly to the Ag+-coated PEEK prepared without H2SO4 (C), while the H2SO4-immersed PEEK-Ag+ adhered strongly enough to withstand being peeled off with tape (D).
